Troubleshooting a gas fireplace can be dangerous. It can cause a heavy amount if something wrong happens. There are a few reasons for fireplace won’t stay lit. What is the main reason the gas fireplace pilot light won’t stay lit? Can you do anything about it?
One of the main reasons for this problem can be not assembling the ignition properly. In some cases, you can fix it by yourself. But I recommended not to. Professional help is always better in appliances like this.
But there is no harm in knowing what and the way is this happening. Let’s take a look at why gas fireplace troubleshoots.
What Causes A Pilot Light To Not Stay Lit?
Before I go into the reason you need to understand what pilot light is.
A pilot light is a small flame that is lit 24/7 and helps to create the bigger flame in the main burner.
Without the pilot light, you would need to manually light the fireplace with a match or something similar to this.
Here are some of them.
1. Ignition Assembly
A pilot light is a part of the ignition system of a gas fireplace. So, when it does not light one of the main causes can be the ignition system is not assembled properly.
When the pilot light is not lighting up the next probable reason may be your fireplace’s thermocouple is bad or worn out.
The thermocouple is a device that senses the gas flow and allows the valve to supply gas to the pilot light.
4. Pilot Tube
A blocked pilot tube can also prevent the pilot light not lighting up. For one season of use, it can be blocked for many reasons. Clearing it up may help light the pilot light.
5. Gas Supply
Many times, simple things like not having a gas supply or a little gas supply can enable the pilot light to light up.
Do not panic instantly when your pilot light is not working. Things like this can easily be fixed if you are a little bit skilled at those kinds of matters.
Other Reasons a Gas Fireplace Won’t Stay Lit
Other than the most common issues there can be some other reasons why your gas fireplace won’t stay lit. here are some of them.
Sometimes incorrect gas pressure is the reason your fireplace is not working. You can measure this gas pressure with a manometer. As it is technical work, it is recommended to call for a technician to do the job for you.
The gas valve is another common reason for which the pilot light or the fireplace can create problem lighting. Make sure it is open for a smooth gas flow.
It is not any of the main causes why fireplaces do not work. But it can cause uneven flames in the fireplace and eventually you will get the worst kind of flame from the fireplace if the burners remain blocked for a long period of time.
Airflow and Venting Issue
In a fireplace, the natural rule is hot air goes up and cool air comes down. If it does not happen for any reason, you are going to face trouble with your fireplace.
Airflow and venting issues come with each other. So, make sure to check both of them altogether.
